When Michigan State University students return this fall, they'll be paying 9.4% more in tuition than the year before, a situation that has irked some state officials. The increase appears to violate a provision in the state budget, which placed a 7.1% cap on raising tuition. Wayne State University is also under scrutiny by state officials, who say its fall increase is 8.4%. Some legislators and a state fiscal agency report say the universities failed to factor increases to tuition for the current summer semester, pushing the real increase beyond the cap.
